It can , since most eating disorders have a compulsive component.
If you have a natural tendency for addiction , hypnotherapy can help your subconscious trigger on other things except that one default action of walking to the cupboard / fridge , where it will get it's dose of endorphins.

well u have to have will power to believe in Hypnotherapy..so in this case i think not....

apparently it works for some people but its best if u combine hypnotherapy with psychotherapy

yes it does work my mother had it done in spain and she lost loads of weight after she had it done cause she also had no will power ..and we took her and it worked.
good luck:)

Hypnotherapy does work for a small percentage of peoples. I have had no experience with it in weight loss, however I did see a therapist concerning smoking cessation. BTW It failed miserably, for me.

well, first you need to program your subconscious mind and then you 'll see results. thru hypnosis and suggestions, you will be able to bypass the critical faculty of your conscious mind. you'll have to program the subconscious to loose weight.
few important tips
a) programming should be specific- dont say i want to loose weight- say - i want to loose 20 pounds.
b) never use negative words - dont think of a black cat- what color cat u thought of ? black, isnt it? dont say - i will not eat sweets- the sub conscious cannot process negative words, instead it will just know - eat sweets.
c) the suggestion should be practical and believable - else the sub conscious will reject it.
d) time bound - all suggestions must be time bound else the sub conscious will not be able to deliver results.
........
now the most important part.
the sub conscious once programmed, you dont have to worry about how you'll loose weight. your conscious mind will get instructions from the sub con to start exercising, eat healthy etc.
you'll have to start exercising and eating healthy.
hypnosis/meditation helps you to get rid of the block or inhibition ad facilitates easier weight loss.
in case you want any help i will send you free audios of sub conscious programming. email me if needed. all the best.

You should just learn how to have a strong will then you can follow your diet...
By doing that you dont need to undergo hypnotherapy...
Just remember what you want and say to yourself that you'll get what you want

it depends on the person and how well you react to the power of suggestion: if you can it works well, if not its a waste of money, you sort of have to have no doubts it will work before you try it or it wont work, maybe you need to actually visually see and talk to someone who has had hypnotherapy, not just read about and see then on tv. What you can do if find a good hypnotherapist and ask about past patients, and if any of them would be happy to talk to you. -then all you have to do is try to believe they havent been paid to talk!

I heard it can but everyone's results will vary just like anything.

hypnotherapy CAN work but its mind over matter...your mind can counter-do whatever the hypnosis programmed you to do. if hypnosis was that simple i think people would go going for all kinds of things. maybe we'd have hynotherapy in prisons!

If you really wanna be realistic then you can lose 4-5 lbs a week. Losing 30lbs should take roughly 6weeks. Simply lower your eating intake by 1/3 and eat as soon as you get hungry. This will increase your body's metabolism and help to burn that excess energy instead of storing it as fat.
(Most importantly avoid light snacks in-between meals as this will increase your food intake without you even realising it).
Also some excercise, nothing too drastic. Just 20 situps in the morning, 20 situps at night before bed. 10 pushups morning and night and some extended brisk walks upto 30minutes a day ( a slightly hilly terain is ideal), and a 15min jog only once a week. (and increase the number of walks/situps etc as you get used to them).
Follow this regime and your 30 lbs should drop within 6 weeks. And the best thing of all you really dont have to drastically change your diet or even exert yourself during excercise. And can actully be enjoyable. With this method, your not actually dieting, it's more of a lifestyle change.
p.s walking on hilly terrain, at steep angles is great, probably the best from of buttock excercise, they get real firm!
